When Apple dropped iOS 7 around a week ago, the world of mobile Apple users clamored to upgrade. After that week of iOS 7 being available, Apple announced that it has been installed on over 200 million devices. Considering iOS 7 is the first time Apple’s mobile operating system has receive an aesthetic overhaul, people couldn’t wait to upgrade. In their haste, though, all of those people that upgraded may have missed that the upgrade is permanent. Once you upgrade, there’s no going back.

Apple’s new OS isn’t a Windows Vista-style situation, where you upgrade only to find that your new operating system is going to make you wish you never owned a computer in the first place. For the most part, it works just fine, and even has a bunch of nifty little hidden features throughout. However, the aesthetic of the OS is completely different, moving from skeuomorphism to large skinny text and flat colors. To some people, the visual style and new animations are too drastic, so a rollback to iOS 6 would be more pleasing on the eyes. Unfortunately for that subset of people, once you go iOS 7, you never go back.

People got the idea in their head of downgrading to iOS 6 during the iOS 7 beta, which allowed users testing the beta to do so. Apple stopped signing iOS 6 installations, which means if you try to install it, you’ll be greeted with an iTunes error. If you tried to downgrade and now your phone is acting wiggy, just restore the phone back to iOS 7, and learn to love Apple’s Lisa Frank version of an operating system. All those bright colors will put you in a good mood next time you scowl at your iPhone screen.
